We're dividing 405121 by 76 
Let's see how many times 76 fits into 405121.

Going ahead to step 1:
When dividing 4 by 76, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 76

Going ahead to step 2:
40 divided by 76 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 76

Going ahead to step 3:
If we divide 405 by 76, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 380 away from 405, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 76

Moving on to step 4:
76 can be fit into 251 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 23 after subtracting 228 from 251.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 76

Going ahead to step 5:
76 goes into 232 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 533.0
If we take 228 away from 232, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 76

Let's proceed to step 6:
When dividing 41 by 76, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 5330.0
Subtract 0 from 41 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
The number 76 fits into 410 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 5330.5
If we subtract 380 from 410, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 76, we get 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 5330.53
Deduct 228 from 300 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
76 can be fit into 720 9 times, resulting in a remainder of 36.
The next digit of our result is 9. 
Result so far: 5330.539
Subtracting 684 from 720 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 76, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 5330.5394
Subtract 304 from 360 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
76 goes into 560 7 times with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 5330.53947
Subtracting 532 from 560 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
The number 76 fits into 280 3 times, leaving a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 5330.539473
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
When dividing 520 by 76, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5330.5394736
The remainder is 64 after subtracting 456 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
When dividing 640 by 76, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 5330.53947368
If we take 608 away from 640, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 5330.53947368 with a remainder of 3.2e-08.
